This invention relates to portable grilles of the type used in place of outside fireplaces or where it is desired to cook outside, such as for picnic use, and in particular this invention relates to grilles formed of a plurality of preformed units whereby the units are readily assembled and used in combination with grates for cooking with a comparatively confined fire.

The purpose of this invention is to provide means for forming an outside grille in which the parts may readily be set up and used as desired or where the parts may be permanently assembled to provide a permanent grille.

Various attempts have been made to provide portable grilles particularly of the type that may be carried in a car and used for picnics, traveling and other outside use, however, the conventional type of grille which is formed of metal parts not only become heated to a high temperature but are dangerous in a high wind. With this thought in mind this invention contemplates a portable grille formed of preformed ceramic shapes wherein the shapes are readily set up to provide a box like grille housing in which means is provided for supporting grates and other cooking elements. The object of this invention is, therefore, to provide means for forming a portable grille wherein the parts are formed with cast or preformed shapes so that they may readily be set up and used as desired.

Another object of the invention is to provide an outside grille having comparatively thick ceramic walls in which the parts may readily be taken down and carried in a motor vehicle.

A further object of the invention is to provide an improved substantially enclosed outside grille which is of a simple and economical construction.

A further object of the invention is to provide an outside grille that may readily be set up of preformed sections which is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a plurality of sections substantially U-shape in cross section wherein one section may be used as a base with the ends thereof extended upwardly and similar sections corresponding to the section forming the base are mounted in upright positions upon the upwardly extended sections, and elongated sections having tongues on the edges positioned to extend into grooves in the edges of the said upright sections, and wherein the said upright sections are provided with means for supporting grates and the like.

Other features and advantages of the inven- 2 tion will appear from the following description taken in connection with the drawings wherein:

Figure 1 is a vertical longitudinal section through the portable grille showing a food holder suspended by a vertically positioned hanger.

Figure 2 is a plan View of the grille with the parts assembled.

Figure 3 is a vertical cross section through the grille taken on line 3-3 of Fig. 1.

Figure 4 is a perspective view illustrating a grille with the parts partly assembled in which preformed sections are positioned upon a similar section providing a base and in which 2. connecting slab is provided in one side.

Figure 5 is a detail illustrating supporting braces used in the corners of the parts.

Figure 6 is a detail showing a section through one side of the grille and showing grates supported on the braces as illustrated in Fig. 5.

Figure 7 is a detail showing a section through the upper part of the grille illustrating the manner of holding product supporting devices such as a roasting spit therein.

Figure 8 is an elevational view showing the upper part of the grille illustrating the handle on the outer end of the roasting spit and showing the handle supported on a horizontally positioned bar.

Figure 9 is a view illustrating one of the preformed-sections with which the grille is formed and in which parts are broken away showing the grate supporting grooves on the inner surfaces.

Figure 10 is a view illustrating a slab that is used between the preformed sections and in which the slab is shown with parts broken away illustrating a section thereof.

Referring now to the drawings wherein like reference characters denote corresponding parts the portable grille of this invention is formed with a base unit channel shape in cross section having a base or web It with flanges H and i2 7 at the ends, a slab is providing a connecting unit, corner braces i l, and a connecting bar 15.

The preformed units are formed, particularly as illustrated in Fig. 9 with grooves l6 and I? in the flanges H and I2, respectively and with tongues l8 and I 9 on the ends of the flanges, and as illustrated Figs. 1, 3, and 4 with one of these units positioned to form a bottom of the grille the tongues I8 and [9 of superimposed units are positioned in the grooves l6 and I1 whereby the superimposed units extend upwardly, particularly as illustrated in Fig. 4.

With these units extending upwardly from the flanges of the bottom unit a slab I3 which is provided with tongues 29 and 2! on the edges, and 22 on one end is positioned with the tongues and 21 extended into the grooves it and H of the upwardly extended units and the tongue 22 at the end extended into the grooves in the edges of the flanges.

These units may be freely positioned or they may be cemented together to provide a perma nent installation.

lhe slab I3 is provided with an opening 23 and with a slab positioned in one side only of the grille as illustrated in Fig. 4, the bar 55, which is provided with slots 2 and 25 is positioned over studs 26 and 21, respectively extended from the flanges whereby a roasting spit, as indicated by the numeral 28 may be suspended in the upper part of the grille with one end resting on the lower edge of the opening 23 and the other on the upper edge of the bar E5.

The inner surfaces of the channel shaped units are also provided with grooves 28 and til that are positioned to hold grates, as indicated by the numerals 3i and 32, in upright positions and, as illustrated in Fig. 1, these grates are positioned to rest upon a horizontally disposed grate 33 that is supported by corner braces it. An additional grate 345, which is also supported by corner braces Ill may be provided at the upper end or the grille and this grate may be provided with a hook 35 as illustrated in Fig. 1 or a plurality of hooks may be used, as shown in Fig. 3 whereby a holder, such as a toaster 38, with a handle 31, may be suspended between the vertically disposed grates BI and 32.

It will be understood that the corner braces i l may be located to support grates in different positions in the grille, such as is illustrated in Fig. 6 where a grate 38 is supported at a point intermediate of the housing or" the grille.

A plate 39 may be provided at the back of the grille to form a closure for the base, as shown in Fig. 1.

With the parts formed in this manner it will be appreciated that the parts may be assembled to form a battery of portable grilles and the parts may be installed without permanently connecting one unit to another or the unit may be permanently connected to provide an outside grille.

The grille may be provided with grates of any type or design and the grates or product holding elements may be suspended in different positions in the grille.

It will be understood that modifications may be made in the design and arrangement of the parts without departing from the spirit of the invention.
